The weight of fiberglass safety helmets is usually between 400-500 grams. This weight range is determined by considering multiple factors such as safety, comfort, and material performance. From a safety perspective, being too lightweight may result in insufficient structural strength of the safety helmet, making it unable to effectively resist impacts and punctures; However, excessive weight will increase the burden on the user's head, affecting work comfort and safety, and easily causing users to be unwilling to wear it properly due to fatigue.

Fiberglass material itself has a high specific strength, that is, a high ratio of strength to weight. The high strength of fiberglass allows for the appropriate reduction of material usage while ensuring the protective performance of safety helmets, thereby controlling weight. Meanwhile, by optimizing the design of the cap shell and cap liner, and adopting a reasonable structural layout, weight can also be reduced without compromising safety. For example, the cap shell adopts a thin-walled design, with reinforcement in critical stress areas and appropriate thinning in non critical areas; The hat lining is made of lightweight materials such as high-strength plastic and breathable sponge, which can provide good cushioning and fixation without adding too much weight.

In addition, the weight of fiberglass safety helmets with different styles and functions may vary slightly. Some safety helmets with special accessories (such as face masks, earmuffs, etc.) may be relatively heavy in weight; However, regular safety helmets are relatively lightweight. But overall, they are within a reasonable range of 400-500 grams to ensure effective protection while maximizing user comfort.
